I agree with you, and: > computers are incomparibly more efficient Yet to be clear the total world energy consumption for computers has increased, which is sad because we could certainly cope with 1/2 of the current total speed capacity but way more efficiency. Trying to get very high TDP chips and/or density is likely going in the other direction (but I could be wrong for the datacenter).
